fxopt is a plugin for GCC that converts floating-point functions to fixed-point arithmetic, primarily for implementation in embedded, real-time systems without floating-point hardware. The conversion is performed in GCC's "middle-end", after the source code has been converted to GCC's intermediate representation but before any target-specific optimizations are done. Several optimization options are available to improve the accuracy of the fixed-point arithmetic, including affine range estimation, rounding, and double-precision multiplications. Fixed-point code produced by fxopt can be significantly more accurate than typical fixed-point implementations with comparable execution time and code size. In many cases the fixed-point code produced by fxopt provides accuracy comparable to single-precision floating-point arithmetic with a factor of 10 faster execution.

AeonWave Audio-FX is real-time, hardware accelerated, cross platform audio effects software for guitar players, singers, vocalists, voice overs, or DJs. Originally designed as an audio effects applet for instrumentalists, it now extends to areas like voice processing for vocalists or live or podcasting DJ work.
Effects include Compressor, Phaser, Flanger or Chorus, Wah, Distortion, and Reverb with echo.

PicoFinance is a stock quote and news reader for any Java (J2ME, MIDP 2.0) or Symbian cellphone. Supporting a configurable portfolio of stock symbols from most world exchanges, it gives users the ability to view current stock prices and other useful financials, breaking headlines and articles, and much more. It allows you to manage a portfolio of stocks, view real-time stock price changes, work with stocks from a variety of world exchanges, keyword search for adding new stocks, view financial details for a stock (P/E, Volume, etc.), see news related to managed stocks, save articles for offline viewing, and share articles using Twitter or SMS/MMS. It has support for JavaScript, images (including GIF, JPEG, PNG, TIFF, and BMP), the ability to zoom, fullsize, save, and OCR images, compression to reduce wireless data charges, and support for Unicode and many character encodings.

METAXPON ("Metachron" in Greek letters) is a small and fast audio DSP library for time-scale manipulation of 16-bit integer or 32-bit floating point stereo audio data streams. It employs a rigid phase-locked vocoder with dedicated transient detection and processing, and can work in real-time or non-real-time. Four editions are included - a portable edition and three x86 editions. The portable edition can be built with any ANSI C compiler and is OS- and architecture-independent. The three x86 editions are written in assembly using the FPU, 3DNow!, and SSE instruction sets, respectively, with automatic selection between them depending on the CPU capabilities. They can be compiled with MASM, JWASM, or NASM, producing libraries of object files in 8 formats.

QoSDB is a QoS registry designed for supporting QoS management in realtime SOAs. It can be exploited for gathering QoS data related to different functional behaviors of the application (application operating modes) and for predicting future performance based on historical data. A modular architecture allows for defining various models for the prediction of resource requirements under a set of conditions which has not been observed yet. This allows for achieving nearly-correct resource allocation (self-configuration) for the application with a great reduction of needed observation/benchmarking points, especially in those contexts in which the space of possible configuration parameters is big (e.g., multimedia applications supporting arbitrary resolutions). By leveraging the QoSDB, SOAs can be built with auto-tuning capabilities, for better exploitation of internal resources while guaranteeing the QoS required by users.

OpenEcoSys-NetworkViewer is a cross-platform Qt4 GUI used to interact with distributed embedded nodes on the network. The modular interface supports multiple transmission media and protocols. Real-time graphical visualization of remote variables hosted on embedded devices is made possible by a software stack called NETVProtocolStack and Arduino compatible boards and Microchip PIC (8,16, 32 bits) micro-controllers are supported. Logging facilities and JavaScript scripting are also available through a plug-in mechanism to interact with the remote variables. A plug-in mechanism is also available to implement new protocols and support new communication hardware.

yuxtapa is a multiplayer real-time CLI game. It looks like a roguelike, but feels like a multiplayer 1st-person shooter with a focus on team play. The idea is to take the "feel" of such team based multiplayer games as Enemy Territory into an NCurses-based game with roguelike controls. Like roguelikes, yuxtapa is lightweight but surprisingly rich under the crude surface. It features several classes from which to choose, each with a different special ability, randomly generated maps which can also be saved and reloaded, and multiple game modes or objectives.

mod_reserve is an Apache2 module for Linux that extends the Apache HTTP server, allowing it to reserve a certain CPU bandwidth for the provisioning of a service.
This module exploits the functionality provided by AQuoSA, whose API is used to reserve CPU bandwidth for execution of tasks. In this way, the module can force the Web server to provide services, like CGI or Perl scripts, using exactly the configured CPU bandwidth. This behaviour is useful in order to provide Quality of Service to certain types of services, or to prevent the kinds of attacks in which a service can starve all the others.

RT-Thread RTOS is a real-time operating system for 16-bit to 32-bit microcontrollers, with components which include a hard real-time kernel, a command line shell, a device virtual file system, and a graphic user interface. RT-Thread/GUI is a graphic user interface integrated with RT-Thread. It provides a multi-window, multi-thread graphic user interface. Rich widgets are implemented in RT-Thread/GUI, such as label, button, checkbox, textbox, etc. The typical RAM usage of RT-Thread/GUI is less than 20kB RAM.
